Perplexity Computer's July update let its agent manage sessions
conversationally from any surface — pin, archive, rename, fork — treating
session organization as operational infrastructure rather than a GUI
nicety. Hermes already has the durable pinned flag in state.db (Desktop
sidebar writes it; auto-archive honors it), but no CLI access existed:
GUI-only management was a single point of failure and blocked scripting
(issue #52955).
- hermes sessions pin <id...> / unpin <id...>: set/clear the durable keep
flag via SessionDB.set_session_pinned (whole compression lineage,
prefix resolution, multi-id, exit 1 on any miss)
- hermes sessions pinned [--json]: list all pinned conversations via the
include_pinned back-fill (old pins can't fall off a paging window);
--json enables backup/restore scripting
- docs: user-guide/sessions.md section
- tests: 6 tests covering prefix resolution, multi-id partial failure,
pinned-only filtering, JSON shape, empty hint
